Our rolling support policy also applies to iOS, Android, Windows Phone, and other devices.

Unsupported Browsers

Outdated browsers are a security risk to you because un-patched vulnerabilities may be exploited by malware or hackers.
They cannot protect your private information and should always be updated.

Internet Explorer 9 and 10
Microsoft ended IE9 and IE10 support on January 12, 2016 — meaning all security updates have stopped.
You should update/switch to a supported browser immediately to protect yourself.

Why We Stop Browser Support

We use cutting-edge web technologies to provide the best experience across the widest range of browsers and devices.
Old browsers simply don’t support many technologies that are common in modern browsers.

We aim for maximum accessibility, but need to draw the line somewhere.
The future is devices of all shapes and sizes.
We’re investing in building fluid multi-device experiences instead of making crutches for 5–10 year old browsers.
